Technical Field
The invention belongs to the field of concrete machinery, and relates to a concrete mixing plant and a mixing plant without an inclined belt.

The concrete mixing plant is a set of equipment for metering, conveying and mixing cement, sand aggregate, water, additive and admixture according to a certain proportion, and has the advantages of high automation degree, high production efficiency, reliable quality of produced concrete and the like, and is widely applied to urban construction, water conservancy and hydropower and road and airport engineering. Through years of development, the concrete mixing plant (station) has been developed greatly at present, but with the environmental protection requirements and the demand being improved, new challenges are met in the development.
The traditional scheme has the advantages of simplicity, easy realization and low cost, but mainly has the following defects:
the concrete mixing plant (station) generally comprises an aggregate storage yard system and a main building system 2, wherein the storage yard system is mainly used for storing gravel aggregates required by various concrete production, such as medium stones, small stones, natural sands, artificial sands, melon seed slices and the like, the main building system is mainly used for storing cement, fly ash, mineral powder, a water reducing agent, a retarder and other powder and additives, and metering and stirring are completed in a main building area to realize concrete production. In the composition of concrete, aggregate generally accounts for 70% -80% of the total volume, in order to realize the stirring of concrete, the aggregate needs to be lifted once or many times, in the existing concrete stirring building (station), the lifting of aggregate mostly adopts an inclined belt conveyor, and is limited by the angle of an inclined belt (for example, the conveying angle of a common inclined belt is generally not more than 20 degrees, the conveying angle of a herringbone belt is not more than 28 degrees, and the conveying angle of a large-inclination belt is not more than 60 degrees), so that the requirement on the site is higher, an aggregate storage yard system and a main building system are separated by a certain distance, the horizontal distance of 30 meters is needed when the aggregate is lifted by 10 meters at most commonly used 18-degree inclined belts of the stirring building (station), if a station type structure is adopted, the lifting height of aggregate is about 15 meters at the main building, the horizontal distance is at least 45 meters, if a building type structure is adopted, the aggregate is lifted to more than 30 meters in the main building, the required horizontal distance is more than 90 meters, although partial problems can be solved by turning the relay through a plurality of belts, the system layout is still limited, and in addition, the arrangement of too many inclined belts in the system causes more interference to the running of transport vehicles and the layout of other equipment because the inclined belts cross the field air.

Furthermore, the material distributing device can be a material distributing belt conveyor, a material distributing trolley or a rotary feeder and the like.
The main characteristic of the standing structure is that the aggregate needs to be lifted for 2 times after coming out from the discharge port of the aggregate storage yard, so that secondary horizontal conveying and secondary vertical conveying are needed. Therefore, the concrete working process of the novel concrete mixing plant without the inclined belt is as follows: aggregate stored in the aggregate storage yard falls onto the first horizontal conveying equipment through the discharge port, enters the first vertical conveying equipment from the aggregate storage yard through the first horizontal conveying equipment, and enters the aggregate transition bin through the distributing device for temporary storage after being lifted. When the production of concrete is started, the aggregates in the aggregate transition bin are measured by the weighing hopper, the measured aggregates drop onto the second horizontal conveying device, the second horizontal conveying device and the second vertical conveying device convey the aggregates into the aggregate hopper, and the aggregates and other measured materials (cement, fly ash, water, additives and the like) enter the mixer together and are mixed to form the qualified concrete.
The invention also provides a novel concrete mixing plant without the inclined belt, and the mixing plant is different from the mixing station in that the main building equipment comprises a material distribution device, an aggregate transition bin, a scale hopper and a mixer; the horizontal conveying equipment is connected with a discharge port at the lower part of the aggregate storage yard, and the other end of the horizontal conveying equipment is connected with an inlet of the vertical conveying equipment; the outlet of the vertical conveying equipment is connected with a distributing device, the distributing device is connected with an aggregate transition bin, and the aggregate transition bin is used for temporarily storing aggregates; the scale bucket is arranged between the aggregate transition bin and the stirrer.
Further, the material separating device usually adopts a rotary feeder.
The building type structure is characterized in that the aggregate transition bin is directly arranged at the top of the stirrer, and directly enters the stirrer after metering without secondary lifting. Therefore, the concrete working process of the novel concrete mixing building without the inclined belt is as follows: aggregate stored in the aggregate storage yard falls to the horizontal conveying equipment through the discharge port, the aggregate enters the vertical conveying equipment from the aggregate storage yard through the horizontal conveying equipment, and the aggregate enters the aggregate transition bin through the distributing device for temporary storage after being lifted. When the concrete is produced, the aggregate in the aggregate transition bin is measured by a weighing hopper, and the measured aggregate directly enters a stirrer together with other materials (cement, fly ash, water, additives and the like) and is stirred to become the qualified concrete.
Compared with the prior art, the invention has the following effects and advantages:
according to the concrete mixing plant and the mixing building without the inclined belt, the horizontal conveying equipment and the vertical conveying equipment are combined, so that the concrete mixing plant and the mixing building without the inclined belt are realized, the requirement of the inclined belt on the space is eliminated, the space is effectively saved, and the utilization rate of a field is improved; and the horizontal conveying equipment is arranged underground, so that the influence on ground buildings and equipment is avoided, and the sealing and dust removal are facilitated.
